ANIMAL WELL (010020D01AD24000)

Update 1.0.10 (v655360), SDK 20.5.7, on NVN (46 BNSH shaders). Modules main and sdk. All its assets, the shaders among them, are embedded in main: the program has no RomFS. The standard host and rewriter run this build with no game-specific fix: no shader overrides, rewriter cuts or host changes. Only this update is registered in the profile. The unsigned IPA is confirmed playable on the iPhone.

On the Mac: the opening rooms at 60 fps with movement, jumping and audio; item pickup and pause menus work. One repeat run recovered from an AudioUnit startup timeout through the existing audio restart path.

What it needs

Setting	Where	Why
romfs_marker empty	game.tsv	the Program NCAs have no data section: nx_extract creates an empty RomFS directory, which the empty marker checks; see Files
3.5 GB layout: mem_reserve 0xe0000000, mem_alias 0x10000000, mem_stack 0x10000000, app_pool 0xCD500000	game.tsv	the provisional layout, which holds: a 256 MB alias region, a 256 MB stack region and a 2816 MB heap region. main sets a heap of at most the pool − 64 MB − 536 MB of bss (counted as used memory)
sys_resource 0x0	game.tsv	the NPDM declares 0 MB of system resource: IsVirtualAddressMemoryEnabled is false, as on Horizon
pad_layout simple	game.tsv	the 2D virtual pad; B jumps
shader_groups /=romfs	game.tsv	the shaders are in main

Files

• Both the base and the update Program NCAs have no data section. The assets live in main, whose read-only segment is about 32 MB.
• Current: nx_extract creates an empty RomFS directory (and a header-only survey manifest) when neither program has a data section. Base and update extraction were checked in both full and manifest modes.

Shaders

• Current: 46 BNSH shaders embedded in main (1 vertex, 45 pixel), all translated for Mac and iOS by the existing splitter and translator. The prewarm list covers the opening rooms.

Memory

• main has about 537 MB of bss, counted by the existing big-module memory rule.
• During a four-minute Mac run, resident memory stayed near 855 MB and Metal allocations at 159 MB.

Found on this game

• An empty RomFS for a program without a data section (nx_extract; an empty romfs_marker checks the directory itself): dm/games/README.md.

Open

• Save and reload are unverified: the test did not reach a save checkpoint.
• The bss is 536 MB in game.tsv's comment and about 537 MB in the bring-up notes (Memory).
• The player-facing README lists the games that start in the 2D layout and says the others start in 3D; ANIMAL WELL is not in that list, but its profile has pad_layout simple (2D).
